State Building Code Council. The State Building Code (SBC) provides a set of statewide standards and requirements related to building construction. The SBC is comprised of various international model codes, including building, residential, fire, and plumbing codes (model codes) adopted by reference by the Legislature. The model codes are promulgated by the International Code Council.
The State Building Code Council (SBCC) is responsible for adopting, amending, and maintaining the SBC. The SBCC must regularly review updated versions of the model codes, and adopt a process for reviewing proposed statewide and local amendments.
Cities and counties may amend the SBC as applied within their jurisdiction, except that amendments may not be below minimum performance standards, and no amendment affecting single or multifamily residential buildings may be effective until approved by the SBCC.
The International Building Code establishes minimum requirements for all buildings except detached one- and two-family dwellings and townhouses up to three stories. The International Residential Code comprises all building, plumbing, mechanical, fuel gas, and electrical requirements for one- and two-family dwellings and townhouses up to three stories
State Elevator Standards. Under current code standards in Washington, in buildings with an elevator, at least one elevator shall provide fire department emergency access to all floors served in:
Elevator cars must accommodate a 24-inch by 84-inch ambulance stretcher. Specified occupancy building types include occupancies containing sleeping units where the occupants are primarily transient in nature—transient congregate living facilities with more than ten occupants, hotels, or motels; permanent occupancies with more than two dwelling units—apartments, dormitories, or vacation timeshare properties; and institutional occupancies—care facilities, or correctional facilities.
By March 31, 2026, the SBCC shall adopt, by rule, standards for cities and counties to allow all passenger and freight elevators to meet the most current version of global safety and related standards, or, in the alternative, the current North American standards.
The SBCC must also adopt standards for cities and counties to allow passenger elevators no larger than those that accommodate a wheelchair for apartment buildings with at most six stories and at most 24 units total.
